View page
US Patent:
6444057, Sep 3, 2002
Filed:
May 26, 1999
Appl. No.:
09/318636
Inventors:
Ramgopal Darolia - West Chester OH

Assignee:
General Electric Company - Schenectady NY
International Classification:
C22C 1905
US Classification:
148428, 420448
Abstract:
An article is formed of a single crystal having a composition, in weight percent, of a modifying element in an amount of from about 0. 2 to about 2. 0 percent by weight hafnium, from about 0. 1 to about 0. 5 percent by weight zirconium, or combinations thereof, and a base alloy composition of from about 4 to about 20 percent cobalt, from about 1 to about 10 percent chromium, from about 5 to about 7 percent aluminum, from 0 to about 2 percent molybdenum, from about 3 to about 8 percent tungsten, from about 4 to about 12 percent tantalum, from 0 to about 2 percent titanium, from 0 to about 8 percent rhenium, from 0 to about 6 percent ruthenium, from 0 to about 1 percent niobium, from 0 to about 0. 1 percent carbon, from 0 to about 0. 01 percent boron, from 0 to about 0.

Turbine Airfoil Process Sequencing For Optimized Tip Performance

View page
US Patent:
6502304, Jan 7, 2003
Filed:
May 15, 2001
Appl. No.:
09/855444
Inventors:
Joseph David Rigney - Milford OH
William Scott Walston - Mason OH
Richard John Grylls - Albuquerque NM
Assignee:
General Electric Company - Schenectady NY
International Classification:
B23P 1500
US Classification:
2988921, 2988922
Abstract:
Optimized tip performance for turbine airfoils is obtained through a sequenced manufacturing process. The turbine airfoils are assembled into the dovetail slots of a turbine disk. The tips of the turbine airfoils assembled in the turbine disk are then measured to determine the turbine airfoils that do not have adequate tip clearance. The tips of those turbine airfoils that do not have adequate tip clearance are then machined to obtain adequate tip clearance. Once all the turbine airfoils have adequate tip clearance, environmental coatings and/or thermal barrier coatings are applied to the blade tips.

View page
US Patent:
6514629, Feb 4, 2003
Filed:
Dec 15, 1998
Appl. No.:
09/210855
Inventors:
Joseph D. Rigney - Milford OH
Ramgopal Darolia - West Chester OH
William S. Walston - Maineville OH
Assignee:
General Electric Company - Schenectady NY
International Classification:
B32B 1504
US Classification:
428632, 428654, 428652, 428670, 428680, 428941, 416241 R
Abstract:
An article such as a gas turbine blade or vane has a superalloy substrate, and a coating system deposited on the substrate. The coating system includes a protective layer overlying the substrate, and, optionally, a ceramic thermal barrier coating layer overlying the bond coat. The protective layer has an uppermost layer with a composition including platinum, aluminum, and, in atom percent, from about 0. 14 to about 2. 8 percent hafnium and from about 2. 7 to about 7. 0 percent silicon, with the atomic ratio of silicon:hafnium being from about 1. 7:1 to about 5. 6:1.

Preparation Of Low-Sulfur Platinum And Platinum Aluminide Layers In Thermal Barrier Coatings

View page
US Patent:
6551423, Apr 22, 2003
Filed:
Sep 8, 1998
Appl. No.:
09/149018
Inventors:
Irene T. Spitsberg - Loveland OH
William S. Walston - Maineville OH
Jon C. Schaeffer - Milford OH
Assignee:
General Electric Co. - Cincinnati OH
International Classification:
C25D 510
US Classification:
148518, 148535
Abstract:
A method for preparing a coated nickel-base superalloy article reduces the sulfur content of the surface region of the metallic coating layers to low levels, thereby improving the adhesion of the coating layers to the article. The method includes depositing a first layer of platinum overlying the surface of a substrate, depositing a second layer of aluminum over the platinum, and final desulfurizing the article by heating the article to elevated temperature, preferably in hydrogen, and removing a small amount of material from the surface that was exposed during the step of heating. A ceramic layer may be deposited over the desulfurized article. The article may also be similarly desulfurized at other points in the fabrication procedure.

Method For Preventing The Formation Of Secondary Reaction Zone In Susceptible Articles, And Articles Prepared By The Method

View page
US Patent:
6843861, Jan 18, 2005
Filed:
Feb 8, 2002
Appl. No.:
10/071129
Inventors:
Theodore Robert Grossman - Hamilton OH, US
Ronald Gustav Rajala - Loveland OH, US
Dwayne Edward Burnett - Liberty Township OH, US
William Scott Walston - Mason OH, US
Wendy Howard Murpjy - Cincinnati OH, US
Assignee:
General Electric Company - Schenectady NY
International Classification:
C23C 804
B32B 1510
B41M 312
US Classification:
148280, 148516, 148535, 228208, 428652, 427142
Abstract:
A coated nickel-base superalloy article, which is otherwise susceptible to the formation of a secondary reaction zone, is prepared by furnishing a nickel-base superalloy article substrate having thereon an initial aluminum-containing coating comprising an initial-coating additive zone and an initial-coating diffusion zone. The article is susceptible to the formation of the secondary reaction zone if heated to an elevated SRZ reaction temperature for an SRZ reaction period of time. The formation of the secondary reaction zone is avoided by first removing the initial-coating additive zone and the initial-coating diffusion zone, and thereafter depositing a subsequent aluminum-containing coating onto the article substrate. The subsequent aluminum-containing coating includes a subsequent-coating additive zone and a subsequent-coating diffusion zone. The article substrate with the subsequent aluminum-containing coating is otherwise susceptible to the formation of the secondary reaction zone if heated to the elevated SRZ reaction temperature for the SRZ reaction period of time.
